Workflow Management System, Uncaught Exception, Un necessary Handler, SetBased Analysis


Exception specification in workflow definition is a means for flexible control flow deviated from normal control flow and adapted to a run time situation. This flexible control flow for unusual situations is particularly useful for long lasting and intricate workflow processes. In this paper, we propose a workflow definition language with exception specification facilities and its analysis method. This lan guage borrows structural constructs and exception handling mechanisms from conventional programming languages. Using this language, process designers can specify excep tions of a process at process build time, and the improper exception specifications can be detected by the analysis method developed in this paper.
